Perfect fit, easy to install, works every time. It was right on target out of the box. The green laser is definitely more visible than my other red laser for older eyes. I’m about to purchase another green CT for my wife’s new 380 Shield (Posted on 3/13/2019)

Great Laser...free IWB holster not so much Review by Kevin

Rating

Thanks to everyone for there reviews, they are why I choose the green laser over the red, and I’m happy I did. The green laser is much more visible in daylight conditions than the red. I’ve put hundreds of rounds through the gun, and the laser has never failed.
I would have given it five stars except for the neoprene IWB holster that came free with the laser. This holster is the most ridiculous thing I’ve ever seen. Buy the laser, toss the holster if they ever offer it again. I’ll be buying CT lasers for all my handguns. (Posted on 2/10/2019)

side plate completely separated Review by scott

I recently ordered the 489G for my S&W .40 and the fit appeared to be extremely nice. When the first round was fired the left laser plate completely dislodged and the plate flew off with the battery. Having owned a number of different lasers I can say this is the first time this has happened. I am unsure if this is a design flaw or a fluke. Either way this is an extremely expensive piece of equipment to break immediately. Especially when this is the exact unit for this specific pistol. Also, there has been zero response from crimson trace about replacing or information as to what happened. I would have to assume this is a safety issue if the screws get stripped when fired. If you want a $300 presentation pointer then purchase this item. (Posted on 3/6/2018)

Bright Green Review by DJ

CTC laser sights are more reliable than iron sights given my eyes. I have both red and green Laserguard sights and the green is incredibly more visible. The green laser came with my M&P Shield 9. The red was purchased separately for my Taurus PT709 Slim. (Posted on 2/17/2017)

great green lazer but poor fit Review by Bill.C

Rating

First of all I own 4 Laser guard products and 3 of them are perfect. My newest LT purchase for my M&P shield, 9mm with the green laser is not close to what I expected from Crimson Trace. while the green laser is very bright and easy to see in the daylight the fitment between the Laser guard and the trigger guard is awful. it snags on clothing and flexes when touched not to mention the ugly visual gap. CT blames the problem on S&W for having two molds which may be true but how is that my problem? This is a very expensive sight but unless you are lucky there is a 50/50 chance it will not fit correctly. Great laser/ Poor fit !

I purchased my S&W Shield9 with the green laser as a package. From day one it has given me great results. My wife purchased her 9mm and laser separately and it was a snap to install. Fantastic lasers with easy on/off. (Posted on 12/3/2016)
